What happened that day?

  • 9 February 2016 — Nikkei 225 fell 5.4%, a little over ten days after the Bank of Japan announced negative interest rates
  • The intent was clear: charge banks for parking money at the central bank so it would flow into lending and investment instead
  • Markets read it differently
  • First, negative rates eat directly into bank profitability
  • Second, going this far was read as evidence every other tool had failed. That the yen strengthened after an easing announcement supported that reading
  • Fell 25.28% from peak — a case of policy working opposite to its intent
